The OPOS6UL Linux distribution can be found here: latest stable installation tarball from SourceForge

Current version

Currently (2017.08) default supported Linux version for OPOS6UL in armadeus BSP is: vanilla 4.8.10. OPOS6UL have been mainlined in Linux from 4.11, so any kernel with higher version number should support this board.

We also support a "legacy" kernel, based on Freescale/NXP 4.1, to have PXP/ALSA functionnalities available until they are fully integrated in vanilla/mainline. Details about this kernel can be found below.
